My only experience with Dell warranties has been with computers. On both occasions the telephone support was excellent, replacement components were shipped out quickly, and in the case of a MB swap a nice man from Stockport visited me on site and swapped the board while I waited, he was extremely methodical and very careful.

Because the computers carry a service tag they were very careful about making sure the machine was covered. I doubt monitors will have service tags but they'll certainly have serial numbers. All the bits the guy replaced had their serial numbers taken down and all the original bits were checked against a list, no chance of swapping a 200G drive for a 20 and hoping they wouldn't notice.

In my experience the warranties have been well worth it, and with something like a TFT a swift reliable service would be very useful.

A dual head setup with those monitors would be very cool.
